Solution:
Given PRQ is a triangle.
ST is a line parallel to RQ.



<u>Triangle proportionality theorem,</u>
<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>


Do cross multiplication, we get

Divide by 2x on both sides, we get

Answer:
To find the surface area of a prism, find the area of a base and double it since the areas of the two bases are always equal. Then find the area of each side face, and add to the area of the bases. A pyramid has one base and triangular sides.
Step-by-step explanation:
Given:
The given expression is

To find:
The two other equivalent expressions.
Solution:
We have,

Using distributive property, we get


So, one equivalent expression is
.
On further simplification, we get


Therefore, the second and fully simplified equivalent expression is
.
Answer:
24 ft
Step-by-step explanation:
Hypotenuse = √9²+16²=√81+256=√400=20ft
the upper side of the stuff = 4 ft
total = 20+4=24
For this case we have that by definition of properties logarithm is met:

So, rewriting the expression we have:

By definition of logarithm we have to:
is equivalent to
So:
